This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.
When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:
# list.of.packages <- c("readxl", "tidyverse", "DT", "leaflet", "palmerpenguins") # List the needed packages
# new.packages <- list.of.packages[!(list.of.packages %in% installed.packages()[, "Package"])] # Of the needed packages, list those not already installed
# if(length(new.packages)) install.packages(new.packages) # Install any packages not already installed
# for (k in 1:length(list.of.packages)) {
# library(list.of.packages[k], character.only = TRUE) # Load the needed packages using library
# }
# rm(list = c("k","list.of.packages","new.packages"))
